Vista Home Edition - internet connectivity issues

By hpm ·

I recently purchased a Compaq laptop and have been trying to get it to connect to the internet consistently. When I use it at home with my Linksys router and cable modem, it fires up just fine. However, when I take it off-site to my office and plug directly into the cable modem there, it will NOT run. I get an IP address that starts with 169... meaning that even though I have set it for automatically getting an IP address from the DHCP, it doesn't assign one. Other folks can plug into the modem and they have NO problems. They are also running Vista Home Edition. I have tried "hard coding" an IP address into my system but that doesn't work either .... any ideas where I should look next?

The following is a suggestion from Peconet Tietokoneet:

He suggested downloading and installing Network Magic:

You might try one other trick:

For network adapter driver, enable TCP/IPv4 and TCP/IPv6, click configure.

The culprit might be TCP/IP v.6

by nepenthe0 In reply to Vista Home Edition - inte ...

Internet Protocol v.6 is enabled by default in Vista, but may not be supported by the office network. Check out True Blue's post of 19 June'08:

Control Panel > View Network Status and Tasks > Manage Network Connections > Local Area Connection

right click Local Area Connection > Properties

> uncheck TCP/IPv.6
> uncheck Link-Layer Topology Discovery Mapper I/O Driver

> uncheck Link-Layer Topology Discovery Responder
click OK > restart

P.S. - If this works, True Blue gets the credit.

Refreshing configuration by using ipconfig /renew
When you troubleshoot a TCP/IP networking problem, begin by checking the TCP/IP configuration on the computer that is experiencing the problem. If the computer is DHCP-enabled and is using a DHCP server to obtain configuration, you can initiate a refresh of the lease by using the command. ipconfig /renew in the command window.

Click Start, run and type in cmd and press Enter.

At the Command Prompt type ipconfig /release and press Enter.

At the Command Prompt type ipconfig /renew and press Enter.

Question for True Blue

by nepenthe0 In reply to Also try this

Does this sequence of commands accomplish the same thing as clicking repair in the LAN icon system tray?

Maybe I can answer....

by ThumbsUp2 In reply to Question for True Blue

Yes, sort of, except at a lower level. It's a command directly to the hardware and leaves Windows out of it. Because, as we all know, sometimes Windows gets confuzzled!

Have you seen the bumper stickers

Keep Portland Weird? Many natives think it's due to influx the past decade from Southern California (Venice Beach types)...

Personally, I prefer the Land of the Tumbleweeds, where one can gaze across miles of unobstructed rolling prairie and hear the meadowlarks chirping.

Reboot the cable modem

by mwhipple In reply to Vista Home Edition - inte ...

Normally cable modems store the MAC address of the device that was last connected and should be rebooted (turned off or unplugged and then powered back on) when connecting a new device (or you could wait potentially quite a while). You may also want to inspect the configuration of the modem itself which is normally accessible through a web interface which could be accessed by a computer than can successfully obtain a lease.
